Tungsten Copper Rod Properties

Tungsten copper rod has excellent mechanical properties and electrical, thermal conductivity, which has a broad application prospect in EDM, heat sink and aerospace fields. It mainly evaluated by density, hardness, conductivity, CTE, wear resistance, tensile strength and so on.


The capacity of resisting a hard object pressed into its surface is called as hardness in physics. And tungsten copper rod hardness is the basic indicator to evaluate the materials if soft or hard.


The capability of current conduction is called as conductivity. Different proportion tungsten copper has different conductivity, which higher Cu content rod has higher electrical conductivity. Usually use σ to represent its conductivity.


Tungsten copper rod CTE (Coefficient of Thermal Expansion) represents the variation of length by temperature changes under constant pressure. And the unit of metal CTE is 1/℃.

Wear Resistance

Tungsten copper rod wear resistance is also called as abrasion resistance or durability, which refers to the capability of rubbing against sand paper, and represented by the reciprocal of wear rate (dt / dV or dL / dV).

Flexural Strength

Tungsten copper rod flexural strength refers to the resistance to bending without broken. It usually uses three-point or four-point test for evaluation.
